Company was established in 2009
Founders had between them 60 years experience in engineering innovative solutions for the
water, environmental, rail and power sectors
EIL’s focus was on the environmental sector with regard to spill, pollution and flood
management
Product focus includes Containment Valves (ASOV’s, ROSOV’s) Flood alarms, Blocked Sewer
Detection, Flow Monitoring and CSO Monitoring, Interceptor and attenuation tanks, as well
as interceptor alarming and monitoring
We have a design and production facility in Hertfordshire, meaning we can react to bespoke
projects
The facility is agile enough to develop new solutions for projects where a one-size-fits all
approach will not work
A cross-section of our Customers include; Travel for London (TfL), Metroline,
Volkerfitzpatrick, Heathrow Airport, DP World London Gateway, DHL, Tescos, Accolade Wines
Flapstopper Valve Background
- The Flapstopper valve has come about as a
result of product development
- Initially, the ‘Drainstopper’ and
‘Telestopper’ offered drain closure solutions
through the means of a bladder
- This product was developed alongside the
EA and Fire Brigade
- Bladders are a high maintenance product,
and become therefore high cost to the client
- Further requirements meant that natural
progression consequentially gave the
Flapstopper (regulation has both progressed
and changed ultimately creating the demand
for a more industrial and hardy solution)
- The Flapstopper came to the market in
2010, and now has circa 150 systems
currently in operation
Flapstopper Valve
- Constructed from 304 stainless steel
- Gasket material to suit the sites needs
- Over-toggle Mechanism
- Dual Acting Cylinder to accommodate the
above
- Compressor in control panel, not cylinder
of air
- Fault functions are fully reportable
- Volt-free termination means that any BMS
or SCADA system can be linked to
- Battery back-up for use when mains power
may fail
- Fully testable (could be daily)
Flapstopper Valve
- Designed to act as ASOV, or ROSOV as per
EA and HSE guidelines when secondary or
tertiary containment is necessary
- Designed to meet BATNEEC, where other
products do not. (The Flapstopper can be
fully retro-fitted through standard manhole
entrances should the correct solution allow
for this)
- Designed to meet EA PPG3, 7, 18, and
assist 21 and 22
- Designed to assist with discharge permits
- Designed to coincide with DEFRA IPPC
where applicable
- Designed to address elements of ISO14001
where applicable
- Designed to meet HSE regulations including
COMAH and standards regarding the storage
of fuel (In wake of the Buncefield incident)

Previous Projects
Wine Bottling Plant - Bristol
Problem
The bottling plant had experienced
numerous spills causing discharges
outside of their pH limits. This was
directly to a brook to the South and lake
to the West Although an existing probe
detected a spill, no mitigating factors
were used
Solution
Two large valves on SW outfall,
automated via pH probe. Wireless
reporting to 24hr manned security lodge.
Battery backup for valve, meaning a
failsafe should mains power fail,
therefore meaning the pH would fail.
Cages around valves in case public access.
Cause
Regular fines avoided. Local wildlife
areas left to recover naturally. PR to local
community shows responsiveness to
environment
Previous Projects
Paint Company - Bolton
Problem
Addressing potential Firewater issues.
Numerous outfalls from site, and
particularly old. Some locations date
from the Victorian era. A penstock
valve on site had been found to be
rusted open
Solution
7 varying size valves to be retro-fitted.
Automation via the sites fire-alarm
panel. Should the alarm sound for a
prolonged period (not drill) wireless
message will close all valves.
Cause
Suitable and efficient EMS with no
eventuality of danger to human life.
All systems can be tested within a
reasonable time frame with minimal
staff.
Johnson Controls
Proposal
The focus is on SW1, is the last
chamber on site to connect differing
neighbourhoods of drainage networks.
These include, the car park to the front
of the site, all roof surface water from
the main building, and then the yard
to the rear.
Three Flapstopper Valves will isolate
all three areas when activated, but can
then be released individually should
this be required.
In addition, the utilisation of
interceptor alarms means that the
automated closure of a valve on a high
oil alarm, mitigates the smaller spill
and hazard risk to the local
environment. This can not be
achieved via one valve on the outflow.
Wireless activation will be confirmed
via a positive closure message to an
independent unit than the transmitter.
Local activation will also be available.

This site had experienced a number of
pollution incidents into the local brook
and pond.
As such, interceptor alarms were
required to officially monitor their
tanks. In addition, having ASOV’s and
ROSOV’s to ensure no pollution was
leaked.
The site had been having emergency
services scheduled for the interceptors
at a phenomenal cost to the business.
The interceptor alarms have meant
that the interceptors are now serviced
individually, and only when the alarms
suggest this should be carried out.
The pollution containment devices
have added their secondary
containment which was lacking
considering the amount of fuels and
oils stored on site. Being able to
activated these remotely has ensured
that no incidents will happen again.
